Yes,.....all my life. The only thing that has successfully, and so far continuously, worked is Prunelax. And this is only within the last couple of months. I am 70. I also mix in psyllium into my oatmeal daily, 8 gm. It is awful to eat but I add diced apples, bananas, and cinnamon. But honestly, I believe it's the prunelax that is really working for me. And what I have noticed on this site is what works for one person, may not work at all for another. But we keep trying things. I wouldn't have even known about Prunlax except through this site. I am currently using 4 mini tabs daily. I understand there is a maximum strength and I am going to try that next, only because I will have to take less tablets. I hope you find something that works for you also! In all my years of dealing with this I found Miralax does not work. I drink lots of water and I use Metamucil wafers when I'm traveling. They're great! I truly understand your situation and the frustration, and even sometimes panic, that it causes. I am wishing you the best. You have to be your own advocate. Jacque
